All That Is Hidden

It’s 1907 in Bowen’s mildly diverting 19th Molly Murphy mystery, the second coauthored with her daughter (after 2022’s Wild Irish Rose), and Molly’s police captain husband, Daniel Sullivan, has some shocking news for her. Despite Daniel’s previous clashes with Tammany Hall, he’s accepted their offer to serve as the city’s sheriff. Plus, he’s agreed to move his family into a fancy Fifth Avenue home that’s a perk of the position. Molly eventually overcomes her anger at not being consulted before her spouse made these decisions, as they lead to multiple mysteries for her to probe. She’s a passenger on a tour boat belonging to Daniel’s corrupt patron, Big Bill McCormick, when a fire breaks out, the second such conflagration on one of McCormick’s vessels, leading her to suspect arson. The authors also toss in a fatal stabbing in a locked room. There are the usual number of contrivances, such as someone rescued from a perilous situation turning out to have an influential parent. This collaboration offers familiar pleasures for series followers. Agents: Christina Hogrebe and Meg Ruley, Jane Rotrosen Agency. (Mar.)
